I prefer to replace a backflow that's been frozen. I don't have a lot of faith that the brass survives the experience without any warping. I don't know whether the Febcos have any problems passing testing, if they've been repaired after a freeze-up. Actual testing requirements haven't yet been legislated by the states around my neck of the woods (NYC) ~ I have a Watts TK-9 at the ready, but it's all dressed up and nowhere to go.

I do tend to look at a PVB in terms of its primary function of a 24/7 vacuum breaker. I don't use the Febco 765, because of the plastic bonnet, which makes it too fragile. A few older designs have brass bonnets, and I've chosen them. If I was looking at a PVB in terms of its pass/fail performance in check valve testing, a different picture might emerge.

Do you have a suggestion of something better I could purchase to replace the Febco 765-1? I was only going to replace it with another one because that is what is there already. If there is something better I should get I would love to get your input.

To all who actually test and repair backflow assemblies you should know by now that anything with the name "febco" is nothing better that a 8 lb. brass paper weight. Lets all do eachother a foavor and never install or replace a febco piece of junk again.

Thanks Tom. I have a Febco 765-1 that needs a few parts replaced and I found out that it is cheaper to just buy a whole new PVB rather then get the parts replaced. I found the 765-100 for a decent price and I just wanted to confirm that it was the same as what I currently have. Thanks again.
